I have T480 with i7 8650u + Nvidia mx150.
Your patch helped me a lot as I was able to undervolt CPU and make my laptop a bit quieter.
Now I wonder if it's possible to unlock advanced Nvidia menu to change current dGPU temperature limit 70°C as it starts throttling way too early.
I found this GUID: 2139B13C-E51A-4E37-B236-DD7A894B111E with reference to NVidiaOptimusAcpi in my dump, hope it can help.
Current bios dump is here.
